This increases performance without\n compromising the signal-to-noise ratio, sound presence, and spatial audio that\n Technics amplifiers are known for.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eJENO Engine\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eJitter, caused by incorrect timing of the master clock used in digital-to-analog conversion, is one of the \nmain sources of distortion in digital systems. To effectively eliminate these influences \non the music signal caused by digital jitter, Technics has developed a completely new \njitter reduction circuit consisting of a clock generator for noise shaping to reduce jitter in the lower frequency range and a high-precision sample rate converter in the higher frequency range. \nFurthermore, Technics uses a newly developed PWM converter assembly to \nexclude errors during conversion to PWM (Pulse Width Modulation). \nThis circuit optimizes the speed of noise shaping, the degree \nof requantization, and PWM gradation to achieve perfect conversion to \nPWM signals without affecting the dynamic range of high-resolution signals. \nThrough these technologies, Technics digital amplifiers impress with natural and the finest nuances in music reproduction.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eADCT (Active Distortion Cancelling \nTechnology)\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe newly developed Technics feature ADCT (Active Distortion \nCancelling Technology) precisely extracts and eliminates distortions in the \npower amplifier stage caused by voltage drops and electromotive effects of the \nconnected loudspeakers, ensuring excellent sound performance with a wide variety of loudspeaker types. \nIt identifies deviations between the loudspeaker output and the JENO output \nand corrects the digital output signal. This ensures powerful loudspeaker operation and strong sound energy, while \nalso offering the superior characteristics of a digital amplifier such as \nlow noise, sharp sound imaging, and expansive sound atmosphere, regardless \nof the connected loudspeaker types.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eLow-noise, stable power supply\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\"Advanced Speed Silent Power Supply\" enables stable performance \nwith low noise\u003c\/p\u003e\u003cp\u003eThe SU-R1000 uses a switching power supply to ensure stable current and \nvoltage supply for the digital amplifier. The Advanced \nSpeed Silent Power Supply eliminates the modulation noise that often impairs sound quality in conventional switching power supplies by placing the switching frequency in the 400 kHz band. \nFurthermore, a Super Low Noise Regulator is used to minimize the noise component in high \nfrequency ranges caused by the fixed switching frequency and the associated reduction in regulation. \nThe result is a power supply with fast response time and high performance.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFour independent power supplies\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTo ensure and further improve the best possible sound quality, \nTechnics has revised every component of the power supply and uses four independent power supply units for \ndifferent circuit blocks in the SU-R1000. In an integrated amplifier like the \nSU-R1000, the internal circuits consist of a preamplifier stage and \na power amplifier stage in a combination of analog and digital circuits. The \nphono EQ, which processes the smallest analog signals, is particularly susceptible \nto noise transmitted via the power supply line. Therefore, the SU-R1000 uses \nseparate power supplies for the analog and digital circuits in the preamplifier stage. \nIn addition, it uses separate power supplies for the left and right power amplifier channels, which require high \npower. Through the four independent power supplies, the \nSU-R1000 effectively prevents line-induced interference between the circuit blocks \nand achieves a high signal-to-noise ratio with superior channel separation.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHigh-quality inputs for high-precision sound reproduction that \nmeets the highest demands\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eBoth the phono input and the analog input circuits feature a fully discrete design. Technics has succeeded in developing an ideal balanced circuit layout with high-precision tuning. Interference between the right and left channels is effectively prevented, and optimal channel separation is enabled. Furthermore, both the phono and XLR inputs use fully balanced transmission to ensure accurate signal transmission with minimal noise. In addition, the USB input circuit is equipped with a high-quality ruby mica capacitor and a power conditioner with magnetic carbon film resistors. This blocks electrical noise, for example from a PC, and minimizes external interference signals. The A\/D converter is equipped with a high-performance chip from Asahi Kasei Microdevices (AKM) for precise analog-to-digital conversion. Excellent sound quality of the SU-R1000 from all analog and digital sources is thus guaranteed.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eExtremely stable housing design\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTo suppress disturbing and sound-impairing vibrations, \nTechnics has comprehensively improved the rigidity of the housing. \nThe inner housing features a double-layered, separated structure. The upper \nsection houses the power amplifier stage, consisting of the amplifier circuit and power supply. \nThe preamplifier section is located in the lower area. It consists of \nthe analog input circuits, including the phono EQ, as well as the \ndigital inputs and their associated power supplies. Both the upper \nand lower sections, as well as the individual circuit blocks, are separated by solid \nsteel shield plates, which also serve to improve the \nhousing rigidity. The front panel is 10 mm thick, while the \nside panels and top cover are made of 6 mm thick alumite-treated \naluminum plates. Furthermore, Technics has been able to improve rigidity and \nvibration resistance. The solid device feet that support the housing \nare made of cast iron with excellent damping properties. By \nusing high-quality components and materials, signal quality is \nsignificantly improved, and the effects of external vibrations are \neffectively eliminated.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eConnections made from carefully selected high-quality \ncomponents\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\n\u003cli\u003e\u003cp\u003eThe \n  loudspeaker terminals allow the connection of cables with particularly large \n  cross-sections\u003c\/p\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cp\u003eY-lugs \n  for a reliable cable connection\u003c\/p\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cp\u003eAnalog, \n  balanced input jacks from Neutrik and phono XLR inputs \n  (MC only)\u003c\/p\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cp\u003eAnalog \n  input jacks with gold-plated, machined \n  brass components\u003c\/p\u003e\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eImproved Technics design\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\n\u003cli\u003e\u003cp\u003eAttractive \n  front panel with high-quality, hairline surface finish and large \n  characteristic VU meters\u003c\/p\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cp\u003eVolume control \n  and input selector milled from solid aluminum block and then \n  polished\u003c\/p\u003e\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Technics","offers":[{"title":"Black","offer_id":54748138635605,"sku":"45052","price":8499.0,"currency_code":"EUR","in_stock":true},{"title":"Silver","offer_id":54748138668373,"sku":"46554","price":8499.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/9715\/6693\/files\/IMG45052_67081.png?v=1787659330","url":"https:\/\/fidelity-hh.de\/en\/products\/su-r1000","provider":"Fidelity","version":"1.0","type":"link"}
